摘要： A distribution panel includes a cabinet having a space formed therein and an inner partition positioned within the cabinet and partitioning a front power transformer (PT) chamber and a rear cable chamber, wherein the inner partition includes: a partition body, on which a bushing is disposed in a penetrating manner, having openings allowing an arc to pass therethrough; and an inner cover rotatably coupled to the partition body to open and close the opening, and rotated by an arc pressure when an arc accident occurs in the front PT chamber, to open the opening. Since an arc from the front PT chamber is spread to the rear cable chamber, pressure of the front PT chamber may be lowered, and a phenomenon in which a PT door is forcibly opened at a high speed is minimized, minimizing an accident.
